Breast Cancer Risk: Red Wine vs. White Wine

Breast Cancer & Wine

After diagnosis, women with breast cancer may cut their risk of dying nearly in half by just instituting simple, modest lifestyle changes—5 or more servings of fruits and veggies a day and walking 30 minutes a day, 6 days a week. But what about preventing breast cancer in the first place?

If we follow the advice of the official dietary guidelines for cancer prevention, does it actually reduce our risk of cancer? If we manage our weight, eat more plant foods, less animal foods, less alcohol and breastfeed, based on the largest prospective study on diet and cancer in history, we may significantly lower our risk of breast cancer, endometrial cancer, colorectal cancer, lung cancer, kidney cancer, stomach cancer, oral cancer, liver cancer, esophageal cancer, and all cancers combined.

Of all the recommendations, the “eat mostly foods of plant origin” appeared the most powerful. For example, a study in the UK found that in just one year in Britain there were 14,902 excess cases of cancer caused by something participants were exposed to 10 years earlier. What was that something that ended up causing thousands of cancers?  

Deficient intake of fruit and vegetables.

If that was instead, some chemical spill causing 14,000 cancers, people would be up in arms to ban it—but instead when that killer carcinogen is not eating their “fruit and veg” (as the Brits would say), it hardly gets anyone’s attention.

What if we throw in smoking, too? Researchers created a healthy lifestyle index, defined by four things: 1) exercise;  2) a dietary shift away from the standard American diet high in meat, dairy, fat, and sugar towards a more prudent dietary pattern—for instance more green and yellow vegetables, beans, and fruits;  3) avoidance of tobacco; and 4) avoidance of alcohol. Young women scoring higher on those four things cut their odds of getting breast cancer in half, older women cut their odds of breast cancer by 80%!

We’ve covered how even light drinking can increase breast cancer risk (see my video Breast Cancer and Alcohol: How Much is Safe?), but for women who refuse to eliminate alcohol, which is less carcinogenic: red wine or white? Some studies, outlined in my four minute video, Breast Cancer Risk: Red Wine vs. White Wine, actually suggest less or even no risk from red wine, and we may have just figured out why. Remember how mushrooms were the vegetable best able to suppress the activity of aromatase, the enzyme used by breast tumors to produce its own estrogen? (from my video Vegetables Versus Breast Cancer). Well, if we run the same human placenta experiments with fruit, strawberries get the silver, but grapes get the gold.

For more on the aromatase story, see:

But what kind of grapes? The wimpy green grapes used to make white wine barely worked compared to those used for making red.  Bottom line: “red wine may serve as a nutritional aromatase inhibitor, which may ameliorate the elevated breast cancer risk associated with alcohol intake.” But why accept any elevated risk? Just eat whole grapes! And if you do, choose ones with seeds if you can, as they may work even better. More on grapes in Fat Burning Via Flavonoids and Best Fruit Juice.

Wasn’t there a study that found that fruits and vegetables weren’t protective against cancer, though? See my video on the EPIC Study.

What if you already have breast cancer? Well, Cancer Prevention and Treatment May Be the Same Thing, but I do have a few studies on breast cancer survival and diet:

  1. I am a fan of cooking with wine, white or red, especially with mushrooms or in spaghetti sauce. I like cooking with wine much better than drinking it, frankly. Does cooking off the alcohol reduce the harmfulness of wine, or does the cancer danger come from something in addition to the alcohol?

    1. Chessie, my guess is the cancer risk associated with alcohol is related to, at least in part, the relatively poor nutritional content per calorie of an alcoholic drink. After all, alcohol is a processed “food” that likely doesn’t have anywhere close to the nutritional content of the original food, not to mention the lack of fiber.

      1. Yes, wine is a lousy deal, nutritionally speaking, but so is soy sauce, or vegetable broth, or vanilla extract, or fruit juice, or any of a number of things we use as flavoring. So if I throw a cup of red wine into a tomato sauce, is that any worse than adding a cup or two of vegetable broth to a stew I’m making? (Sodium aside, of course.) I don’t foresee wine ever being more than a trivial part of my calorie intake.

    2. It would be a good choice to opt for Organic wine wherever possible:

      To be considered certified organic wine, the winery cannot use harmful pesticides, herbicides or synthetic fertilizers. Also, the wine must be all of that AND not have any sulfites. Unlike the USDA’s rules for all other organic products, wines must be 100% organic – not 70%.

    1. Always opt for the Whole food if possible. In this case, Organic Whole Red Seeded Grapes. The darker the skin, the better. Chew well.

  2. Long ago, I heard there was some indication that daily wearing of underwire bras increased chance of developing breast cancer. It sounded plausible enough so I determined to skip that risk and only choose wireless from then on. Whereas at one time there were few, now there are many wireless options to choose from when bra shopping.

  3. Not advocating the use of alcohol but for those who are uber interested in all things vegan check out this app: or if you don’t have Apple products go to There may be others but I know of this one.

    Also, while on the subject: I am trying out a new app: “Is It Vegan?”. Kinda fun as you can scan a product, you can “treat sugar as vegan” or not as well. They don’t have every product in there but I think they are adding to their database regularly.

    Full disclosure: I have ties to either of this apps or website.

    But if its a whole food – no need for apps!

  4. I know this isn’t the right place for this question, but there are only a handful of videos that even mention the placenta and this is one. Is there any research for against ingesting your placenta after you give birth? It seems to be an increasingly popular thing to do. Those for it make it seem like my baby is going to miss out on key nutrients if I don’t do it, but it seems weird to me. Does science have anything to say about this?
